Let's divide 428987 by 81
We want to figure out the number of times 428987 can be divided by 81.

Let's proceed to step 1:
The number 81 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 81

Step 2:
The number 81 fits into 42 0 times, leaving a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Fetch the next digit (8) from the dividend, attach it to 42 and continue: 428 / 81

Let's proceed to step 3:
The number 81 fits into 428 5 times, leaving a remainder of 23.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 405 from 428 leaves us with 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 81

On to step 4:
The number 81 fits into 239 2 times, leaving a remainder of 77.
Use 2 as the next digit of our solution. 
Result so far: 52.0
If we take 162 away from 239, we end up with 77.
Bring next digit (8) of the dividend behind the 77 and repeat the process: 778 / 81

Let's proceed to step 5:
81 goes into 778 9 times with a remainder of 49.
Use 9 as the next digit of our solution. 
Result so far: 529.0
The remainder is 49 after subtracting 729 from 778.
Include the next digit (7) from the dividend after 49, then repeat: 497 / 81

Step 6:
81 goes into 497 6 times with a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 5296.0
If we subtract 486 from 497, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
If we divide 110 by 81, we get 1 and a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 5296.1
If we subtract 81 from 110, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 8:
81 can be fit into 290 3 times, resulting in a remainder of 47.
The next digit of our result is 3. 
Result so far: 5296.13
Subtract 243 from 290 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 9:
When dividing 470 by 81, we get 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 5296.135
The remainder is 65 after subtracting 405 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 10:
The number 81 fits into 650 8 times, leaving a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 5296.1358
If we subtract 648 from 650, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
20 divided by 81 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 5296.1358
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
When dividing 200 by 81, we get 2 with a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 5296.135802
The remainder is 38 after subtracting 162 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 13:
When dividing 380 by 81, we get 4 with a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 5296.1358024
Subtract 324 from 380 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 14:
If we divide 560 by 81, we get 6 and a remainder of 74.
Record the quotient 6 as the next digit in the result. 
Result so far: 5296.13580246
Deduct 486 from 560 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

The final outcome is 5296.13580246, with a leftover of 7.4e-08.
